'Stu Hood and Brian Degenhardt talk about the history of Scala at Twitter, from inception until today, covering 2.10 migration, the original Alex Payne’s presentation from way back, pants, and more. The first five years of Scala at Twitter and the years ahead!'

Excellent stuff. Using "sljit", a stackless platform-independent JIT compiler, this compiles Perl-compatible regular expressions to machine code on ARM, x86, MIPS and PowerPC platforms, resulting in 'similar matching speed to DFA based engines (like re2) on common patterns' with Perl compatibility. 'This work has been released as part of PCRE 8.20 and above. Now (PCRE 8.31), nearly all PCRE features are supported including UTF-8/16 and partial matching.'

A counter-argument: "so, redo, from a conceptual point of view, has a really good and simple approach (very djb-y), and I'm sure it's an excellent tool for new projects, but for existing projects that already use make in a non-recursive fashion, it would a maintenance PITA. And that's why I conclude that redo in its current conceptual state will never be the Git of build systems. make is still more flexible, and even though it has its flaws, it's still good enough for most people, and also a de-facto standard."
